'EDUARDO -seuiiinarnnrI or LIQUID-soar' nrs-marsan.-

Be it known that I, EDUARDO SQUADRiLLi,

' .a citizen of the Kingdom of italy, residing in New York, in theborough of Brooklyn,

.county ofglKings, and lState of New York,

have invented certain new'and useful'lmprovements-in Liquid-'SoapDispensers, of

y which t-lie following is a specification.

This invention relates to an improved dispenser for' liquid soap bywhich apredetermined qu'antit of liquid soap is discharged by a Simp emanual operation for use in the' toilet-rooms of hotels, restaurants,

publie buildings etc., so that the use of a cake of 'soap by-.dierentparties and the non-hygienic influence of the same is avoided.

In'the. accom anying drawings, Figure l represents a si e-elevation ofmy improved liquid soap dispenser, Fig. 2 is apvertical longitudinalsection of the same, Fig. 3 is a detail sideview of the hollow slidingpiston for producing the discharge of the liquid soap from the`receptacle, and Fig. 4 is a vertical transverse section on line 4,4,Fi-g. 3. Similar letters of reference 4indicate correspending partsthroughout the several figures.

'Referring to the drawings, a represents a receptacle for liquid soap,which may be made of glass or other suitable material.

l and of spherical,- oval`= or other shape. The

cap a1 is removed an .receptacle a is provided at its upper end `'with`a removable screw-cap a1 having a central opening a2: When thereceptacle a is to be filled' with liuid soap, the screW then replacedafter illing the saine;

LI) represents a tubular bracket-arm which is provided with anattaching; pflate b1 hav- '2 or securing l the device to a wall or othersuitable sup- -port. The tubular bracket b is provided with two tubularportions (l, di which extend in line with each other at right-anglesJEUto the horizontal portion or" the bracket, the

upper tube d. being provided with an interiorly-threaded seat al? forreceiving the exteriorly-threaded lower end or neck a of the receptaclea. The tubular bracket b1 is provided at diametrically opposite pointswith ports or openings 01 and 03, the former affording communicationbetween the interior of said tubular bracket and thensupply pipe d andthe latter affording communication 19e- Infthe tubular portion oflthebracket 1i' is arranged a tubular piston f which is openat the innerend, the stem f1 of which is guided in the opening `of a screw-cap b4,

lwhich is screwed over' the exterioily-'threaded end of the tubularfront-portion of the bracket-arm b. An elastic packing ring isinterposedbetween. the head ofthe piston f and the screw-cap 'b4 so as to'preventany escape of' liquidsoap along the stem of the piston. The stem f1 isprovided at its outer end with a.l push-button f2 which is attached onthe end of the stem. ffl, as shown clearly in Fig. 2. Y

Between the' partition b3 (if the bracket- .arm Z) and the head of thetubular piston is integposed a helical s ring f3. which is Naw YORK, u.Y., AssIGNoR oF ONE-FOURTH 'ro ARTHUR, Amana, or New Yoan, ir-. Y.

locate'd in the tubular portion of the piston f. l

The tubular piston f is provided aloiig its side with a longitudinalgroove f* which is engaged by a fixed screw f5, that passes tion of thebracket b and engages the longitudinal groove f* of the piston so .as toprevent the turning of the piston on its 4through a small opening in thetub'ular por-.

axis during its inward or outward motion.

The tubular piston f is provided at its upper part with aninlet port or.opening v0, which registers in the normal position of the piston withthe corresponding opening 01 atl the lower end of the upper tube. rl, sothat the liquid' soapcan pass' from the 'receptacle a Athrough vtheupper tube d and the openings 0-1 0 into the interior of the pistn andinto the tubular front-portion of the ,bracket I) filling this spaceentirely with liquid soap. The piston f is further provided at its lowerpart, but at a distance 'in front of the opening o about equal to thelengthof said opening with a 'second opening 02, which regis? ters withthe upper end of the lower tube or discharge-spout'ai1L when the pistonis forced inwardly.` During 4the inward? motion. of

; vthe .piston .pressurelis exertedson the-liquid `1c charge-tube areplaced in register and a cerin the tubular portion bf the bracket, which'as long as the opening o of the piston comand the cylindricalfront-portion of the tube municates with the opening o1 at the ,lowerend of the supply-tube d permits the liquid to be pressed upwardlythrough these openings, but as soon as the o ening o passes the openingo1 and is out ci) register with the same, the openin o2 in the lowerpart of the piston and t e opening 03 of the distain quantity of liquidejected through the spout' d1. On releasing the 4knob of the pistomrod,the spring f3 returns the piston into its form-er normal position sothat the liquid can be again .supplied through the openings o, 01 to theinterior of the piston The quantity of liquid discharged at, each inwardmotion of the piston is approximately the same.-

lThe pistonvis preferably operated by the right hand and the liquid soapdelivered onto the left hand, ,which is held below the discharge-spoutand-then used for cleaning the hands. v

As soon as thepressure on the push-button f2 is relaxed, the helicalspring f3 ref turns the piston into normal position, so thatthe'openings o ando1 are again placed in register. As the liquid soap inthe receptacle is under atmospheric pressure, a new supply of liquidsoap is supplied to the interior space of the piston so as to replacethe quantity of liquidsoap-discharged previously by the inward'motion ofthe piston. The operation of pushing the iston iii-- wardlyand'dischar'ging the predliatermined quantity of liquid soap can then berepeated until the entire quantity of liquid soap' in the receptacle isused up.

The liquid soap dispenser can be used for discharging other liquidmaterials, such as toilet cream, medicated or perfumed oils anddisinfecting or any other substances, so that the dispenser can be usedfor ladies toilet rooms and in connection with Washbasins in public orprivate places.

In the use of this liquid soap dispenser a uniform quantity of .liquidsoap or other substance is positively discharged by the pressure of thepiston on `the liquid, so that scenes absolutely the same quantity isdischarged at every-inward pressure of the same, While the same quantityvis replaced by gravity fromthe 'receptacle into the space at theinterior of the piston.i This renders the function'of the dispenseruniform and reliable,

lespecially when the liquid thickens after some time and assumes acertain consistency,

the piston'will still force out the quantity required. The apparatusdoes not leak and the soap or other liquid does not deteriorate as thereis but little access of air tothe same.

v This dispenser presents a symmetrical appearance wit its supply anddischarge pipes disposed at diametrically opposite points, and itshollow piston, operative in connection with. the so disposed pipes,causes -the soap coutainedin the liquid receptacle supported by thebracket to be forcibly discharged. at a convenient point.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is:`

A dispensing apparatus-for liquid soap or similar substances, comprisinga tubular bracket provided at one end with attaching means and at theother end with a closing device and interinediately with lateral supplyand discharge pipes disposed opposite each other, a'liquid receptaclesecured to said supply pipe, a reciprocating tubular piston disposed insaid tubular bracket and provided with an inlet port on its upper sideadapted to register when the piston is in outward position with saidsupply pipe, and with an outlet port on' its under Side forwardof saidinlet port a distance about equal to the length of said port and adaptedto register when the piston is pressed inward with said discharge pipe,a spring for normally holding said hollow piston in outward position,and means for preventing the rotation of said piston.

'In testimony, that I claimthe foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
